Article 29(5) of the Constitution of Russia states, "The freedom of the mass media shall be guaranteed. Censorship shall be prohibited."
New York Times, March 4, 2022:
Russia clamped down harder Friday on news and free speech than at any time in President Vladimir Putin’s 22 years in power, blocking access to Facebook and major foreign news outlets, and enacting a law to punish anyone spreading “false information” about its Ukraine invasion with up to 15 years in prison.
The crackdown comes as the Kremlin scrambles to contain discontent over the war and to control the narrative as Russia faces its most severe economic crisis in decades as a result of this week’s crushing Western sanctions. Fearing prosecution, more independent Russian news outlets shut down on Friday, and the BBC said it had suspended all of its operations in Russia.
How will Russians get reliable information? The Wikipedia article at the top states, again:
"The freedom of the mass media shall be guaranteed. Censorship shall be prohibited."
